Tax havens are countries that offer low or no tax rates to foreign individuals and businesses in order to attract capital. They provide secrecy and flexibility in business regulations. Many multinational corporations and wealthy individuals use tax havens to avoid paying taxes in their home countries by routing profits through shell companies in havens. This reduces government tax revenues and allows corporations and individuals to escape legal accountability. Critics argue tax havens exacerbate inequality and financial instability, while supporters view them as legitimate tools for business competitiveness and individual choice.
